DUST-COLLECTOR.

SFECIFCATION forming part of Letters Patent No. 397,048, dated January 29, 1889.

Application filed Marcil 23, 1887. Serial No. 232,205. (No model.)

To (LZZ 107mm it 'nm/y concern,.-

Beit known that I, EUGENE BRETNEY, a citizen ol. the United States, residingI in the city of Indianapolis, county ot Marion, and State of Indiana, have invented certain new and useful Improvements in Dust-Collectors; and I do hereby declare the following` to be a itull, clear, and exact description oli' t-he invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

This invention iielates to machines for collecti n g dust and asserting the same according to the specific gravity oi' the particles forming the dust, and is adapted ,t'or use in itlour and other mills; and it has for its object to provide a simple, durable, and inexpensive device whereby a current ot' dust-laden airmay be purilied in the most thorough manner in one machine or during one treatment; and it consists ot' the parts and combinations ot' parts hereinailfrr described and claimed.

In the aceoinpamfing drawings, forming a part oi' this specilieatiini, Figure l is a plan view oi my machine, partly broken away to show the interior; Fig. il, a vertical section on the line a', lr'ig. I; and Fig. l,a horizontal section on the line 1/ 2/, Fig. 2.

L:Similarletters re'ler to sim i larparls throughout the several views.

E represents a cylindrical. shell and l) an inverted conical shell, the upper end of which is hcrmetically secured to the lower end o't the shellE. The upper end of shell E is provided with an air-tight cover or head, O, having a central opening, over which or to the edge of which the lower end of a cylinder, B, is secured in such manner as to prevent the escape ot air at the point olf connection. This cylinder ,ll is also provided with an air-tight cover or head, i l', having a central opening, throi'lgh'which passes and liowhich is secured a tube or evliinler, A, the upper end ol which vis provided with a valve, n, whereby the passage ot the air lhrough the tube Vmay be regulated.

At a slight distance above the lower edge ol shell E and within the same a dividingpartition or ring, v', is secured in the manner hereinafter described, through which the tube or cylinder A extends, the ring and cylinder being connected so as to form an air-tight joint. Between the ring r and the cover O olf the shell E a series ot curved dellectors, e, are secured obliquely in a circular line about the cylinder A, but at a distance therefrom-that is, the inner edges ot' the dellectors terminate on a line with the wall of the cylinder B and are secured at their upper ends to the cover O and at their lower ends to ring r, thus supportin said ring.

lVithin the conical shell l) an inverted conical shell (V is secured bv aitachine` it at its upper end to the inner edge ot the rin gII, thus termin g a chamber Vli'or th e dust-laden aircurrent, which passes through the opening e. A short conical shell, l?, surrounds the shell C, and is secu red at its upper end to the outer edge or periplniryr ot the ring ll, the purpose ol' which shell will be explained hereinafter. Said ring lll is secured to the cover O Vin any suitable manner (bolts 71 being indicated) in position to form an annular opening, c, between its inner edge and the outer edge o 'l the ringf/1 anda similar opening between its outer edge andthe casingE. In said rin Il a number of openings are madc,throngh which and correspondingl openings formed in the cover O a series ol tubes, d, having valves in at their upper ends, are passed. At the side of each ot" these a de'tleetoigfi. is mounted and extends out at. an angle corresponding substantially in direction to the angle of the de tlectors c.

All three of the conical shells are open at their lower ends, and shells C and D terminate on a line or level with each other, and may be provided with any suitable devices to convey away the collected dust, while the shell F terminates at a short distance below the upper end olf conical shell (V, the tubes d being located immediately above and opening into said shell F.

An opening is formed in the side ol cylin* der I3, to which is Iitted aspout, Vp, said spout being connected with the machine from which the dustis drawn, and it may be provided with the fall f io ereaie ille draft or aeeeleraie ille current oi (lnSidaden l'lirljlassin through ille spout.
